    <p>Before launching <span class="APPLICATION">Privoxy</span> for the
    first time, you will want to configure your browser(s) to use
    <span class="APPLICATION">Privoxy</span> as a HTTP and HTTPS (SSL)
    <a href="http://en.wikipedia.org/wiki/Proxy_server" target=
    "_top">proxy</a>. The default is 127.0.0.1 (or localhost) for the proxy
    address, and port 8118 (earlier versions used port 8000). This is the one
    configuration step <span class="emphasis EMPHASIS c2">that must be
    done</span>!</p>

    <p>Please note that <span class="APPLICATION">Privoxy</span> can only
    proxy HTTP and HTTPS traffic. It will not work with FTP or other
    protocols.</p>

    <p>With <span class="APPLICATION">Firefox</span>, this is typically set
    under:</p>

    <p>Or optionally on some platforms:</p>

    <p>Then, check <span class="QUOTE">"Use Proxy"</span> and fill in the
    appropriate info (Address: 127.0.0.1, Port: 8118). Include HTTPS (SSL),
    if you want HTTPS proxy support too (sometimes labeled <span class=
    "QUOTE">"Secure"</span>). Make sure any checkboxes like <span class=
    "QUOTE">"Use the same proxy server for all protocols"</span> is
    <span class="emphasis EMPHASIS c2">UNCHECKED</span>. You want only HTTP

    <p>After doing this, flush your browser's disk and memory caches to force
    a re-reading of all pages and to get rid of any ads that may be cached.
    Remove any <a href="http://en.wikipedia.org/wiki/Browser_cookie" target=
    "_top">cookies</a>, if you want <span class="APPLICATION">Privoxy</span>
    to manage that. You are now ready to start enjoying the benefits of using
    <span class="APPLICATION">Privoxy</span>!</p>

    <p><span class="APPLICATION">Privoxy</span> itself is typically started
    by specifying the main configuration file to be used on the command line.
    If no configuration file is specified on the command line, <span class=
    "APPLICATION">Privoxy</span> will look for a file named <tt class=
    "FILENAME">config</tt> in the current directory. Except on Win32 where it
    will try <tt class="FILENAME">config.txt</tt>.</p>

    <div class="SECT2">
      <h2 class="SECT2"><a name="START-REDHAT" id="START-REDHAT">5.1. Red Hat

      <p>A default Red Hat installation may not start <span class=

      Windows</a></h2>

      <p>Click on the <span class="APPLICATION">Privoxy</span> Icon to start
      <span class="APPLICATION">Privoxy</span>. If no configuration file is
      specified on the command line, <span class="APPLICATION">Privoxy</span>
      will look for a file named <tt class="FILENAME">config.txt</tt>. Note
      that Windows will automatically start <span class=
      "APPLICATION">Privoxy</span> when the system starts if you chose that
      option when installing.</p>

      <p><span class="APPLICATION">Privoxy</span> can run with full Windows
      service functionality. On Windows only, the <span class=
      "APPLICATION">Privoxy</span> program has two new command line arguments

      <p>During installation, <span class="APPLICATION">Privoxy</span> is
      configured to start automatically when the system restarts. You can
      start it manually by double-clicking on the <span class=

      <p>After downloading the privoxy software, unzip the downloaded file by
      double-clicking on the zip file icon. Then, double-click on the
      installer package icon and follow the installation process.</p>

      <p>The privoxy service will automatically start after a successful
      installation. In addition, the privoxy service will automatically start
      every time your computer starts up.</p>

      <p>To prevent the privoxy service from automatically starting when your
      computer starts up, remove or rename the folder named
      /Library/StartupItems/Privoxy.</p>

      <p>A simple application named Privoxy Utility has been created which
      enables administrators to easily start and stop the privoxy
      service.</p>

      <p>In addition, the Privoxy Utility presents a simple way for
      administrators to edit the various privoxy config files. A method to
      uninstall the software is also available.</p>

      <p>An administrator username and password must be supplied in order for
      the Privoxy Utility to perform any of the tasks.</p>

      <ul>
        <li>
          <p><span class="emphasis EMPHASIS c2">--version</span></p>

          <p>Print version info and exit. Unix only.</p>
        </li>

        <li>
          <p><span class="emphasis EMPHASIS c2">--help</span></p>

          <p>Print short usage info and exit. Unix only.</p>
        </li>

        <li>
          <p><span class="emphasis EMPHASIS c2">--no-daemon</span></p>

          <p>Don't become a daemon, i.e. don't fork and become process group
          leader, and don't detach from controlling tty. Unix only.</p>
        </li>

        <li>
          <p><span class="emphasis EMPHASIS c2">--pidfile FILE</span></p>

          <p>On startup, write the process ID to <span class=
          "emphasis EMPHASIS c2">FILE</span>. Delete the <span class=
          "emphasis EMPHASIS c2">FILE</span> on exit. Failure to create or
          delete the <span class="emphasis EMPHASIS c2">FILE</span> is
          non-fatal. If no <span class="emphasis EMPHASIS c2">FILE</span>
          option is given, no PID file will be used. Unix only.</p>
        </li>

        <li>
          <p><span class="emphasis EMPHASIS c2">--user
          USER[.GROUP]</span></p>

          <p>After (optionally) writing the PID file, assume the user ID of
          <span class="emphasis EMPHASIS c2">USER</span>, and if included the
          GID of GROUP. Exit if the privileges are not sufficient to do so.
          Unix only.</p>
        </li>

        <li>
          <p><span class="emphasis EMPHASIS c2">--chroot</span></p>

          <p>Before changing to the user ID given in the <span class=
          "emphasis EMPHASIS c2">--user</span> option, chroot to that user's
          home directory, i.e. make the kernel pretend to the <span class=
          "APPLICATION">Privoxy</span> process that the directory tree starts
          there. If set up carefully, this can limit the impact of possible
          vulnerabilities in <span class="APPLICATION">Privoxy</span> to the
          files contained in that hierarchy. Unix only.</p>
        </li>

        <li>
          <p><span class="emphasis EMPHASIS c2">--pre-chroot-nslookup
          hostname</span></p>

          <p>Specifies a hostname to look up before doing a chroot. On some
          systems, initializing the resolver library involves reading config
          files from /etc and/or loading additional shared libraries from
          /lib. On these systems, doing a hostname lookup before the chroot
          reduces the number of files that must be copied into the chroot
          tree.</p>

          <p>For fastest startup speed, a good value is a hostname that is
          not in /etc/hosts but that your local name server (listed in
          /etc/resolv.conf) can resolve without recursion (that is, without
          having to ask any other name servers). The hostname need not exist,
          but if it doesn't, an error message (which can be ignored) will be
          output.</p>
        </li>

        <li>
          <p><span class="emphasis EMPHASIS c2">configfile</span></p>

          <p>If no <span class="emphasis EMPHASIS c2">configfile</span> is
          included on the command line, <span class=
          "APPLICATION">Privoxy</span> will look for a file named
          <span class="QUOTE">"config"</span> in the current directory
          (except on Win32 where it will look for <span class=
          "QUOTE">"config.txt"</span> instead). Specify full path to avoid
          confusion. If no config file is found, <span class=
          "APPLICATION">Privoxy</span> will fail to start.</p>
        </li>
      </ul>

      <p>On <span class="APPLICATION">MS Windows</span> only there are two
      additional command-line options to allow <span class=
